Abstract

Compositions are provided that can include R F (R T ) n Q, and/or R Cl (R T ) n H. The R F group can have four fluorine atoms, the R T group can include a C-2 group having a pendant —CF 3 group, n can be at least 1, the R 1 group can include a carbon atom, the R Cl group can be —CCl 3 , and the Q group can include one or more atoms of the periodic table of elements. Telomerization processes are also provided.

Claims

exact text as granted — not AI-modified
1 - 14 . (canceled)  
     
     
         15 : A composition comprising: 
 R Cl (R T ) n H, wherein: 
 the R Cl  group comprises at least —CCl 3 ;  
 the R T  group comprises at least one C-2 group, the C-2 group comprising a —CF 2 — group and at least one pendant —CF 3  group; and  
 n is at least 1.  
   
     
     
         16 : The composition of  claim 15  wherein n is at least 2 and the composition comprises  
       
         
           
           
               
               
           
         
       
     
     
         17 : The composition of  claim 15  wherein n is at least 2 and the composition comprises  
       
         
           
           
               
               
           
         
       
     
     
         18 : A telomerization process comprising exposing at least one CF 3 -comprising taxogen to a fluorine-comprising telogen to produce a telomer, wherein the fluorine-comprising telogen comprises at least two fluorine atoms.  
     
     
         19 : The process of  claim 18  wherein the CF 3 -comprising taxogen is pentaluoropropene.  
     
     
         20 : The process of  claim 18  wherein the fluorine-comprising telogen is .(CF 3 ) 2 CFl.  
     
     
         21 : The process of  claim 18  wherein the exposing the CF 3 -comprising taxogen to the fluorine-comprising telogen is in the presence of an initiator.  
     
     
         22 : The process of  claim 21  wherein the initiator comprises a peroxide.  
     
     
         23 : The process of  claim 22  wherein the peroxide comprises di-tert-butyl peroxide.  
     
     
         24 : The process of  claim 22  wherein the exposing occurs within a reactor and the initiator and telogen are provided to the reactor, a mole ratio of the initiator to the telogen being between about 0.001 and about 0.05.  
     
     
         25 : The process of  claim 24  wherein the mole ratio of the initiator to the telogen is between about 0.01 and about 0.03.  
     
     
         26 : The process of  claim 19  wherein the exposing occurs within a reactor, a temperature within the reactor during the exposing being from about 130° C. to about 150° C.  
     
     
         27 : The process of  claim 18  wherein: 
 the CF 3 -comprising taxogen is pentafluoropropene; and    the telomer comprises                          wherein: 
 the R F  group comprises at least two fluorine atoms;  
 n is at least 1; and  
 the Q group comprises one or more atoms of the periodic table of elements.  
   
     
     
         28 : The process of  claim 18  wherein: 
 the CF 3 -comprising taxogen is pentafluoropropene;    the fluorine-comprising telogen is (CF 3 ) 2 CFl; and    a mole ratio of the taxogen to the telogen is from about 2:1 to about 4:1.    
     
     
         29 : The composition of  claim 15  wherein the R T  group is
